Single-electron transistor effect in a two-terminal structure
A peculiarity of the single-electron transistor effect makes it possible to
observe this effect even in structures lacking a gate electrode altogether. The
proposed method can be useful for experimental study of charging effects in
structures with an extremely small central island confined between tunnel
barriers like a nanometer-sized quantum dot or a macromolecule probed with a
tunneling microscope), where it is impossible to provide a gate electrode for
control of the tunnel current.Comment: 5 pages, 2 figure
Preparation of the Sm3+-doped magnetic nanoparticles via microwave-assisted polyol synthesis
Sm3+-doped magnetic nanoparticles (NPs) were prepared via microwave-assisted polyol synthesis in ethylene glycol, poly(ethylene glycol) and mixed ethylene glycol - poly(ethylene glycol) solutions. In present work, the effects of organic solvent composition on particle size, particle size distribution, extent of agglomeration, and samarium content in prepared NPs were studied. The synthesized NPs were characterized by several techniques as follows: X-ray diffraction (XRD), transmission electron microscopy (TEM), thermogravimetry (TGA) and X-Ray fluorescence (XRF) analysis. XRD and TEM results showed formation of ~6.0 - 17.9 nm NPs having different microstructure characteristics (average particle size, particle size distribution, and agglomeration
Structural studies of magnetic nanoparticles doped with rare-earth elements
Magnetic nanoparticles and those doped with rare-earth metal ions having spinel structure were synthesized, possessing the average particles size of 11.3-13.4 n

Association of C3435T (rs1045642) polymorphism of the MDR1 gene with the increased risk of colorectal cancer in russian females from Central Russia
The objective of this study was to examine associations of single nucleotide polymorphisms, rs1045642 within the MDR1 gene and rs1799930 within the NAT2 gene, with the risk of colorectal cancer (CRC) in the population of Central Russi
Oscillating nematic aerogel in superfluid 3He
We present experiments on nematic aerogel oscillating in superfluid He.
This aerogel consists of nearly parallel mullite strands and is attached to a
vibrating wire moving along the direction of the strands. Previous nuclear
magnetic resonance experiments in He confined in similar aerogel sample
have shown that the superfluid transition of He in aerogel occurs into the
polar phase and the transition temperature () is only slightly
suppressed with respect to the superfluid transition temperature of bulk
He. In present experiments we observed a change in resonant properties of
the vibrating wire at and found that below an additional
resonance mode is excited which is coupled to the main resonance.Comment: 6 pages, 6 figure
